1 Samuel 17:50-52

Darby Translation

⁵⁰ So David overcame the Philistine with a sling and a stone, and smote the Philistine and killed him; and there was no sword in the hand of David.

⁵¹ And David ran, and stood upon the Philistine, and took his sword, and drew it out of its sheath, and killed him completely, and cut off his head with it. And when the Philistines saw that their hero was dead, they fled.

⁵² And the men of Israel and of Judah arose, and shouted, and pursued the Philistines, until thou comest to the ravine and to the gates of Ekron. And the wounded of the Philistines fell down on the way to Shaaraim, even to Gath, and to Ekron.
